Check Point (CHKP-11.6%) joins security hardware peer Fortinet (FTNT-17.9%) in tumbling post-earnings. Though Check Point's Q3 results were respectable, the firewall vendor guided on its call for Q4 revenue of $355M-$387M and EPS of $0.84-$0.91 vs. a consensus of $381.8M and $0.90. The big question: to what extent is the guidance the result of soft IT spending and strong European exposure, and to what extent is it due to competition from Palo Alto Networks (PANW-1.2%) and its disruptive next-gen firewalls?
